RAILWAY-GAR oHocK.

SPECIFICATION forming` part of Letters Patent No. 659,051, dated October 2, 1900. Application led July 10, 1900. Serial No- 23116. (No modelll To all whom, it may concern,.-

Be it known that I, .IoHN T. CoNDoN, of Le Mars, in the county of Plymouth and State ot' Iowa, have invented a new and useful Improvement in Railway-Oar Chocks, of which the following is a specification.

My invention is in the nature of a railwaycar chock designed to arrest the motion of railway-cars when switched onto a siding and prevent them from passing onto the main track again. When cars are switched onto a siding, it sometimes happens that the cars will by reason of too great momentum or failure of the brakes pass off the siding and onto the main track again, involving the risk of a wreck by collision with through trains.

My invention is designed to provide a simple and practical device for preventing the cars from passing oi the side track; and it consists in the special construction and arrangement of parts hereinafter described, in which-- Figure l is a side elevation of my device with the rails and road-bed of the side track in cross-section. Fig. 2 is a plan View.

In the drawings, A A represent the rails of a side track. Two of the cross-ties B B of the side track are extended out to one side and upon them is erected an upright frame O of the kind used in an ordinary railroadswitch. A base-plate D is fixed to these cross-ties below the frame O, and to this baseplate is fulcru med an upright hand-lever E, bearing a broad signal-face at its upper end: The lower end of this. lever is jointed to a horizontal. connecting-rod F, disposed in an underground channel below the cross-ties and jointed at its`other end to the slotted lower end of a chock-lever G. This lever is fulcrumed on a rod-H, passing through the extended cross-ties and occupies a posit-ion just inside one of the rails of the track. Its upper end is provided with a hook-shaped beak a, which when the lever is in upright position, as shown, laps over the rail from its inside face and projects outwardly over the rail, as shown, if the cars should leave the siding with too much momentum or their momentum should not be adequately arrested by the brakes the wheels of the car striking the hooked end of the chock-lever will be thereby arrested and brought to a standstill, and if the momentum be excessive the curved upper end of the beak and its outwardly-directed point act to throw the car oft' the track and stop it in this way instead of risking its passage onto the main track in the path of dangerous collisions with rapidly moving through trains.

When the lever E is set and fixed by bolt I, the latter is secu red by a padlock I', as seen in Fig. 2.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A railway-car chock consisting of an upright chock-lever fulcrumed below the rails to vibrate in a plane at right angles to said rails, and having at its upper end a hookshaped beak arranged to be projected across one of the rails or be withdrawn from the same, a connecting-rod arranged below the road-bed, and extending to one side of the track, and an upright lever connected to said rod and provided with locking devices substantially as described.
